CodeConditionStatement Class

Represents a conditional branch statement, typically represented as an if statement.

CodeConditionStatement can be used to represent code that consists of a conditional expression, a collection of statements to execute if the conditional expression evaluates to true, and an optional collection of statements to execute if the conditional expression evaluates to false. A CodeConditionStatement is generated in many languages as an if statement.

The Condition property indicates the expression to test. The TrueStatements property contains the statements to execute if the expression to test evaluates to true. The FalseStatements property contains the statements to execute if the expression to test evaluates to false.

This example demonstrates using a CodeConditionStatement to represent an if statement with an else block.

// Create a CodeConditionStatement that tests a boolean value named boolean.
CodeConditionStatement conditionalStatement = new CodeConditionStatement(
    // The condition to test.
    new CodeVariableReferenceExpression("boolean"),
    // The statements to execute if the condition evaluates to true.
    new CodeStatement[] { new CodeCommentStatement("If condition is true, execute these statements.") },
    // The statements to execute if the condition evalues to false.
    new CodeStatement[] { new CodeCommentStatement("Else block. If condition is false, execute these statements.") } );

// A C# code generator produces the following source code for the preceeding example code:

// if (boolean) 
// {
    //     // If condition is true, execute these statements.
// }
// else {
//     // Else block. If condition is false, execute these statements.
    // }        
    

// Create a CodeConditionStatement that tests a boolean
// value named boolean.
CodeConditionStatement conditionalStatement = new 
    CodeConditionStatement(
// The condition to test.
new CodeVariableReferenceExpression("boolean"),
// The statements to execute if the condition evaluates to true.
new CodeStatement[] { new CodeCommentStatement("If condition is true,"
    + "execute these statements.") },
// The statements to execute if the condition evalues to false.
new CodeStatement[] { new CodeCommentStatement("Else block. If "
    + "condition is false, execute these statements.") });
// A VJ# code generator produces the following source code for the
// preceeding example code:
// if (boolean) {
//     // If condition is true, execute these statements.
// }
// else {
//     // Else block. If condition is false, execute these statements.
// }
